Problème d'initialisation avec Hibernate
Bonjour,
j'essaie en vain de faire fonctionner Hibernate dans Netbeans mais mes tentatives restent sans succès..

Concernant ma datasource je l'ai testé avec du jstl et elle fonctionne parfaitement...
Est-ce l'emplacement de mon fichier User.hbm.xml?
car voici le message qui est stocké dans exception:
"resource: User.hbm.xml not found"
Est-ce qu'il y une feinte concernant l'emplacement des fichiers xml?
